Description

technical field [0001] The invention relates to the technical field of experimental instrument electronic equipment, in particular to an embedded intelligent liquid viscosity coefficient measuring device and a measuring method. Background technique [0002] In some experiments and studies on the properties of liquids, there is a demand experiment for measuring the viscosity coefficient of liquids. The falling ball method is usually used in the experiment. This method generally needs to manually measure the distance and time for the ball to fall at a constant speed in the liquid. Since it is necessary to measure the distance and time of the ball falling in the liquid, this method is only suitable for liquids with certain transparency. These shortcomings have brought a lot of inconvenience in actual measurement. Disadvantage 1: For transparent liquids, manually measuring the falling time and judging from experience that the current ball is moving at a uniform speed will bri...
